INTRODUCTION<\/h2>\n

A pair of terminals through which a current may enter or leave a network is known as a port. Most of the circuits we have dealt with so far are two-terminal or one-port circuits, represented in fig. (a). We have considered the voltage across or current through a single pair of terminals-such as the two terminals of a resistor, a capacitor, or an inductor. We have also studied four-terminal or two-port circuit involving op-amps, transistors and transformer as shown in fig. (b). Thus, we can say that a two-port network is an electrical network with separate ports for input and output.
\nIn general, a network may have n ports. In this chapter, we are mainly concerned with two-port networks (or simply, two ports).<\/p>\n
